CORNER-LOCK FOR BEDS OR THE LIKE.

Application filed July 7, 1816.

To all whom it may concern:

Be it known that'l, Buarivnrr MoIN'rosH, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Corner-Locks for Beds or the like, of which the following is a specification.

This invention relates to bed-steads, andmore particularly provides an improved coupling for corner-post and side-rail.

The coupling member which constitutes the invention, preferably embodied as a single unitary casting, includes a socket for receiving the side-rail end when the bedstead is assembled. A tail-piece or plate is ofiset from the closed end of the socket and carries devices for interlocking with cooperant devices on a familiar-coupling member carried by the cornerpost. A rib or side wing is laterally offset from the socket and arranged perpendicular to the plate, for supporting the bed spring. The various elements of the casting are so designed, proportioned, disposed and webbed together that a casting of extreme lightness but of very great strength is provided, for cooperating in a novel manner with the other parts of the bed-stead and with the bedspring.

The invention will be most clearly understood from the following description, when taken in connection with the accompanying drawing, of which- Figure 1 is a perspective view of the complete bed, assembled;

Fig. 2 is an enlarged detail view, illustrating the coupling in side elevation;

Fig. 3 is a view similar to Fig. 2, but showing the coupling members interlocked, and disclosing a modification in that the two members are bolted together;

Fig. fl is a section on the. line 4.-l of Fig. 3; and

Fig- 5 is a perspective view of the unitary side-rail casting looking to the right of Fi 2.

The assembled bed shown in Fig. 1 includes head and foot sections 6 and 7. siderails 8, and a bed-spring 10 comprising head and foot angle-irons 9 and a mattress-supporting wire-structure made up of a net 11 and coil-springs 11 connecting th net and the angle-irons.

sections are each sleeved by a casting 13, sweated on. As shown best in Figs. 2 and 4, each casting 13 consists of the main tubular portion 14 which surrounds the corner-post and a longitudinally offset plate 15. This plate is formed to provide an upper recess 16, a lower recess 17 and a binding edge 18. The two recesses are arranged one vertically below the other, the binding edge being inclined downwardly and away from the corner post. This casting 13 forms a structure the general features of which are familiar in the art.

Fly improvement concerns itself solely with the provision of a novel device embodied also as a single casting. Such novel casting is indicated at 19 in Fig. 2 and shown in perspective in Fig. 5. Four of these castings 19, carried by the side-rails 8 as indicated in Fig. 1, are adapted to act not only as companion fasteners to the four castings 13 on the corner-posts 12 and thus permit the side-rails S to be readily coupled and locked to the head and foot sections 6 and 7, thereby to assemble the bed, but also to act as direct supports for the angle-irons 9 of the bed-spring 10.

As shown best in Figs. 2, 1 and 5, my cast ing 19 includes a horizontal tubular part or socket 20 for receiving an end of a side-rail 8. Laterally ofiset from the socket is a rib or transverse wing 21, and longitudinally offset from the socket is a tail-piece or plate 22. A web 23 joins the web and socket. The web 23 and the plate 22 are parallel, but in staggered relation, with the web arranged above the axis of the tubular socket.

The plate 22 is recessed as indicated at 24, and thus the plate near its top is disconnected from the wing 21; but the joining of the plate 22 and the wing 21 is reinforced by a lug which is formed on the casting between the plate and wing at a point just above the joining of the wing to the socket 20. This lug as well as upper and lower pins and 27 formed on the plate 22, are all arranged on the side of the plate 22 nearest the axis of the socket and hence lie opposite the web 23 overlying the socket.

The cylindrical wall of the socket 20 is shaped so that the length of the roof of the socket is equal to the length of the base of the Web 23, but the floor of the socket is much shorter. A lug 28 may be provided. not only to strengthen the joining of the plate 22 to tie socket, but also to strengthen the lloor and end-Wall 29 oi' the socket.

.lletore the bed asseinhled,

parts to he interlocl'ed to build up Each side-rail 8 is nreterahlv tubular w l 3 i L provided at eacn end with a notch or 30 which engages the lug 28 when the socl of the casting 19 within which the lug formed receives a rail end. The "tour castings 19 may be permanently secured to the ends of the two side-rails.

in assembling the bed, the

side-rails equipped With their castings 1.) are first connected to the cornenposts 12 as each casting l9 advanced toward its conipanion casting; on a corner-post, th post is held lined in substantially a vertical position, While the rail is so guided that the plate 22 supported on the rail is arranged. relatively to the plate supported on the post as shown in and then the plate is lower alongside and in contact With the plate 15 until the pins 26 and 27 enter the recesses 16 and 17 and the lug 25 binds and loclts against edge 18 as shown in Fig. Jitter tl side-rails S are thus connected. to the corner-posts 12, the lied-spring 10 is arranged in place as indicated, the dependent Yerti *al members of angle-irons 9 entering 24-. and the lnn'lzontal members of the angle-irons resting on the flat upper edges of Wings 21. i

It may be desirable to prorine a special and supplemental interlocking incani plates 15 and 22 as iere the bed is to he used in a hospital, iisane cliylllill or the like. In such a case th two plates are transversely apertured in such a- Way that the apertures will register when the bed is assembled so that a bolt may he passed through the apertures and a threaded on the bolt. Thus i einhled plates 15 and ar reg ring ap hol zitending throng-h thew h "d 1 clan'iped tight by a not 33 tl 1 ded on JOl Th apertnres Bl. are tonne-cl as 1 in. orde;

For it is clear that a light Weight and easily handled lied-spring, that is, one similar to the lied-spring 10 in that rigid side-rails for the hed ,pring are dispensed with, Will have peculiar and valuable characteristics. In he first place, when the bed-spring 10 is once placed in position on Wings 21, it may not be displaced lengthwisely of the bed. soon as a Weight is placed on the spring, eren the Weight of a light mattress, the angle-irons areroclted snl'liciently in the reces 4 to hind their lower edges tight against the plates 22. and then the beds ring may not he displaced laterally of the bed.

I claim:

In a corner fastener, the combination of a corner post, a plate secured to the corner post provided With vertical outstanding re- 5 cessed portions and an intermediate bind ing edge, a side ail, a wing plate provided With a socket on its rear face to receive the side rail and a vertical outstanding plate on its front face said vertical outstanding 10 plate provided with project-ions adapted to Copies of this patent may be obtained for five cents each by addressing the Commissioner engage in the recessed portions of the corner post plate, and an integ'a-l transverse lug arranged at the juncture of the vertical outstanding plate and the Wing plate and adapted to cooperate with the binding edge on the corner post plate to frictionally lock the parts in position.

In testimony whereof I ailix my signature.
